Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a filtration device for resveratrol extraction. Background Technology

[0002] In current technologies, cerebral aneurysms are a serious cerebrovascular disease threatening human health, with an incidence rate as high as 5%, and a high mortality and disability rate. Currently, only vascular intervention and craniotomy are available for treatment, but these methods have drawbacks such as high trauma, high mortality, easy residual disease after surgery, and a relatively high recurrence rate. Non-invasive drug-based conservative treatment may be one of the effective ways to delay the development of cerebral aneurysms and reduce the risk of rupture. Resveratrol is a natural polyphenol widely found in red grapes, Polygonum cuspidatum, blueberries, peanuts, and red wine. It is believed to have various health benefits, including antioxidant, anti-inflammatory, and anti-cancer properties. Through its powerful antioxidant and anti-inflammatory effects, it can reduce the damage of inflammatory factors to the blood vessel wall and help maintain the structural stability of the blood vessel wall. Related studies have shown that resveratrol can prevent cerebral aneurysms. Currently, resveratrol production requires extraction from fermented materials using an extractant. However, the existing filtration devices used in the resveratrol production extraction process have poor filtration efficiency, failing to adequately filter the material. Furthermore, the filtration structure cannot be disassembled and replaced according to actual needs, resulting in poor flexibility in use.

[0003] Chinese utility model patent application number 202420609132.3 discloses a resveratrol extraction and storage device, including a base and a filter screen. A fan is fixedly connected to the middle of the base, three support rods are fixedly connected to the top of the base, a storage cylinder is fixedly connected to the top of the support rods, a protective cover is fixedly connected to the top of the base, a motor is fixedly connected to the left side of the protective cover, a rotating shaft is fixedly connected to the drive end of the motor, a stop block is fixedly connected to the right side of the rotating shaft, a discharge cylinder is fixedly connected to the middle right side of the storage cylinder, and a discharge port is fixedly connected to the bottom right side of the discharge cylinder. However, this resveratrol extraction and storage device can only perform single-stage extraction of resveratrol and cannot perform dual-stirring extraction, resulting in a low resveratrol extraction rate.

The replenishing component is used as a backup communication channel between the extraction tank 2 and the liquid dispensing container 15.

[0026] The replenishment assembly includes a replenishment pump 24 and a replenishment pipe 25. The replenishment pump 24 is located on the side of the extraction tank 2 near the liquid dispensing mechanism and is fixedly connected to the extraction tank 2 via a bracket.

The replenishment pipe 25 passes through the dust cover plate 19. The replenishment assembly, through the cooperation of the replenishment pump 24 and the replenishment pipe 25, forms a spare communication channel between the extraction tank 2 and the liquid dispensing container 15. The replenishment pump 24 serves as the power source between the extraction tank 2 and the liquid dispensing container 15. The structure is designed to introduce the resveratrol solution in the extraction tank 2 into the outlet container 15. The replenishment pipe 25 is used to connect the extraction tank 2 and the outlet container 15. Under normal operating conditions, the resveratrol solution in the extraction tank 2 is introduced into the outlet container 15 through the connecting pipe 21 via the connecting pump 23. When there is too much resveratrol solution in the extraction tank 2 and it is necessary to improve the solution export efficiency, the replenishment component is activated. The replenishment pump 24 introduces the resveratrol solution in the extraction tank 2 into the outlet container 15 through the replenishment pipe 25, forming a dual-channel connection structure, thereby effectively improving the export efficiency of the resveratrol solution.

[0028] In this technical solution, the mesh size of the secondary filter cartridge 11 is greater than that of the primary filter screen 10, thereby effectively improving the filtration accuracy of the resveratrol solution.

[0029] The sealing strip between the opening baffle 17 and the liquid outlet container 15 can effectively improve the sealing performance and sealing accuracy between the two, and prevent leakage.

[0030] Working principle: When the equipment is started, the solenoid valve 22 opens, and the drive unit activates the primary and secondary stirring components. Plant materials containing resveratrol are added to the extraction tank 2. The primary and secondary stirring components perform a dual stirring extraction operation on the plant materials. The pump 23 pumps the resveratrol solution from the extraction tank 2 into the outlet container 15 via the connecting pipe 21. The outlet container 15 temporarily stores the resveratrol solution. When the resveratrol solution needs to be discharged, the sealing is controlled by the electronic control unit 26. When cylinder 16 operates, the output end of the opening cylinder 16 retracts to drive the opening baffle 17 to rise. The resveratrol solution in the liquid receiving box 15 is discharged through the liquid guide channel 20, thus entering the next process for further extraction of resveratrol. When there is too much resveratrol solution in the extraction tank 2 and it is necessary to improve the solution export efficiency, the liquid replenishment component is activated. The liquid replenishment pump 24 introduces the resveratrol solution in the extraction tank 2 into the liquid receiving box 15 through the liquid replenishment pipe 25, thereby improving the export efficiency of the resveratrol solution in the extraction tank 2.

[0031] The beneficial effects of this utility model are that it is equipped with an extraction mechanism, which adopts a double filtration extraction structure to perform double stirring extraction on plant raw materials containing resveratrol, effectively improving the extraction rate of resveratrol. It is equipped with a liquid outlet mechanism and a connecting mechanism, which can quickly introduce the resveratrol solution in the extraction mechanism into the liquid outlet mechanism through its dual-channel connecting structure, and automatically discharge the resveratrol solution, thereby improving the efficiency of resveratrol extraction and processing and meeting the needs of large-scale resveratrol extraction.

All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
